High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...

This app note provides a simple circuit to drive high brightness LEDs. It requires minimum external components and it provides both linear and PWM dimming. Ideal for Osram, Lumileds, Cree, and Nichia ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Schaffner has added the ED100/ED101 EMC filter series for LED driver circuits. The new filter’s common-mode inductance is matched by a substantial differential-mode inductance. With only one component ...
